摘要
在通信中 ,正弦波 (余弦波 )常用来调制信号。事实上 ,实矩形波、三角波、梯形波等波形在电子学中已经广为应用 ,它们结构简单 ,易于在工程中实现。现以梯形波构成的梯形波系为研究对象 ,介绍它的主要性质 。
It is main contradiction between the limited frequency resource and the mass demand required.Trapezoidal wave,Square wave and Triangular wave,which have been widely applied in practice, are common waves in electronics.Trapezoidal wave's main properties is introduced,and a kind of multi channel communication system model is provided by biorthogonal property in the idea condition.At the same frequency resource,this model's system capacity istwice bigger than the model designed by orthogonal property.
